Some Agronomic Studies in Chickpea (Cicer arietinum L.) and Lentil (Lens culinaris Medik)

Bu çalışma, nohut (Cicer arietinum L.)’ta farklı fosfor ve azot dozları ile mercimekte (Lens culinaris Medik) farklı azot dozları ve bitki sıklığı denemesi olarak 4 farklı deneme sonucunu içermektedir. Araştırma, iki yıl süreyle (2010-2012) Diyarbakır’da yürütülmüştür. Araştırma sonuçlarına göre; nohutta farklı fosfor dozlarının bitki boyu, bitkide dal sayısı ve 100 tohum ağırlığına etkisi önemsiz bulunmuştur. İlk başlangıç dozu olan 15 kg P ha-1 ve 30 kg P ha-1 tane verimini arttırmıştır. Farklı azot dozlarının nohutta bitki boyu, bitkide dal, bakla ve tane sayısı ve tane verimine etkisi önemli bulunmuş, 20 kg ha-1 azot uygulaması nohut tane veriminde artış sağlamıştır. Mercimekte farklı fosfor dozlarının bitkide bakla ve tane sayısına etkisi önemli, tane verimi ve hasat indeksine etkisi önemsiz bulunmuştur. Mercimekte farklı bitki sıklıklarının bitki boyu, bitkide bakla ve tane sayısı, tane verimi, biyolojik verim ve hasat indeksine etkisi önemli olup, 200 tohum m-2 bitki sıkılığı en yüksek, 100 tohum m-2 bitki sıkılığı ise en düşük tane verimi vermiştir.

Nohut (Cicer arietinum L.) ve Mercimek (Lens culinaris Medik)’te Bazı Agronomik Çalışmalar

This study consisted of four different experiments in chickpea (Cicer arietinum L.) and lentil (Lens culinaris Medik): phosphorus fertilizer doses in chickpea and lentil, nitrogen fertilizer doses in chickpea and sowing rates in lentil. Studies were conducted at Diyarbakir in Southeast Anatolia of Turkey over two years (2010-2012). The experiment of phosphorus fertilizer doses in chickpea revealed that the effect of phosphorus on plant height and number of branches plant-1 and 100 seed weight was non-significant and with starter dose of 15 kg P ha-1 initially increased the yield and 30 kg P ha-1 application increased in chickpea. The effect of nitrogen fertilizer doses on plant height, number of branches, pods and seeds plant-1 and grain yield was significant, and the high grain yield was obtained from 20 kg N ha-1. The effect of phosphorus doses on number of pods and seeds plant-1 was significant, but grain yield and harvest index was not significant in lentil. The effect of plant population densities on plant height, number of pods and seeds plant-1, grain yield, biological yield and harvest index was significant. The highest grain yield was obtained in 200 seed m-2 sowingrates, (compared to low density seeding rate of 100 seed m-2) but grain yield from 100 seed m-2 was low.
